Lightweight and compact with optical separation, significantly improved brightness accuracy and measurement range!
The "BM-9A" is a lightweight, compact, and portable handheld luminance meter. As a successor to the long-popular "BM-9," it maintains a similar price while significantly improving luminance accuracy and measurement range. By selecting and exchanging three types of light sensors with different measurement angles, it can be used for a wide range of applications. Additionally, the light sensor can be separated from the main unit, making it suitable for use in system devices and production lines. 【Features】 ■ Handheld, low-cost, multifunctional ■ Three types of light sensors can be selected and exchanged, automatically recognized, and measurement results displayed directly ■ Built-in USB for communication with PCs and use in production lines and system devices ■ Keyboard unit allows selection of correction factors and deviation measurements For more details, please contact us or download the catalog.
